Research Abstract |
First, the barium titanate (BT)/BT nano-structured ceramics, whichBT nanoparticles (size: 300 nm) were strongly connected at 3-dimention, were prepared witha relative density of 60 %, and their dielectric constant was 800 while the piezoelectricconstant was 100 pm/V . Then, the potassium niobate (KN)/BT/BT nano-structured ceramics,which their open pores were epitaxially loaded by KN, were prepared with a relative densityof 80 %, and their dielectric constant was 1800 while the piezoelectric constant was 300 pm/V .
